HEAD requests should never have a body in their response, even if there are

errors (such as 404s).

  >>> response = http(r"""

  ... HEAD / HTTP/1.1

  ... """)

  >>> print str(response).split('\n')[0]

  HTTP/1.1 200 Ok

  >>> print response.getHeader('Content-Length')

  0

  >>> print response.getBody()

  <BLANKLINE>

  >>> response = http(r"""

  ... HEAD /badurl HTTP/1.1

  ... """)

  >>> print str(response).split('\n')[0]

  HTTP/1.1 404 Not Found

  >>> print response.getHeader('Content-Length')

  0

  >>> print response.getBody()

  <BLANKLINE>

Register a test page that generates HTTP 500 errors.

  >>> from zope.app.testing import ztapi

  >>> class ErrorView(object):

  ...     """A broken view"""

  ...     def __init__(self, *args):

  ...         oops

  ...

  >>> ztapi.browserView(None, "error-test", ErrorView)

Do a HEAD request on the error test page, and check that its response also has

no body.

  >>> response = http(r"""

  ... HEAD /error-test HTTP/1.1

  ... """)

  >>> print str(response).split('\n')[0]

  HTTP/1.1 500 Internal Server Error

  >>> print response.getHeader('Content-Length')

  0

  >>> print response.getBody()

  <BLANKLINE>
